Significant Slowing of my MacBook Air

This app. looks good. However, it significantly slowed my MacBook Air (mid. 2013 model, w/Sierra & 8 GB memory). Other apps. were slow to open. Previously, my MacBook Air opened apps. quickly and they operated with very good speed. After I deleted this app., my MacBook Air returned to it previous fast performance.

This app. works very well on my iMac (w/Sierra & 16 GB memory), without slowing the performance of other apps.
